SJ Koch Electric Boats, Oxon Hill

S.J. Koch Duffy's electric boats are eco-conscious, as they don't burn any fuel. Emitting zero emissions, the 22- and 18-foot rental boats provide breathtaking views upon departure. Renters can take the canopied vessels floating by Annapolis's US Naval Academy. On board, a built-in stereo system emits an energetic score to each renter's adventure. Duffy's website claims the boats are as easy to drive as a golf cart, but also offers training for new drivers.
